Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of LED light string production equipment, and in particular to a light string clamping mechanism for LED light string production. Background Technology
[0002] PVC-insulated string lights, also known as PVC-insulated string lights, differ from traditional LED string lights. Traditional LED string lights consist of a lamp head and two insulated wires connecting the lamp head to each LED unit. These LED units are connected in series to form the string. A key characteristic of traditional LED string lights is the V-shaped structure formed by the lamp head and the two insulated wires, making the lamp head protrude and less aesthetically pleasing. PVC-insulated string lights, on the other hand, conceal the lamp head within the insulation, resulting in a more aesthetically pleasing and elegant appearance.
[0003] To achieve automated production of drop wire light strings, as disclosed in announcement number CN214840234U, a fully automatic disc-type drop wire light string production device includes a disc clamping and conveying mechanism and a wire guiding mechanism, a cutting mechanism, a stripping mechanism, a chip welding module, and a glue injection mechanism arranged sequentially around the disc clamping and conveying mechanism. The disc clamping and conveying mechanism is used to clamp the drop wire and intermittently convey the drop wire along a circumferential route. The wire guiding mechanism is used to guide the drop wire into the disc clamping and conveying mechanism. The cutting mechanism is used to cut the drop wire. The stripping mechanism is used to press down the cut drop wire to expose the copper wire inside the drop wire. The chip welding module is used to weld the chip to the copper wire. The glue injection mechanism is used to inject glue into the copper wire to encapsulate the chip.
[0004] The disc clamping and conveying mechanism is used to clamp and convey the wires, and together with the wire mechanism, it completes the wire introduction. For this purpose, it needs to realize the automatic opening and closing of the clamp. However, the existing clamps are prone to problems such as jamming, unstable clamping, and inability to open during use, which affects the operation of the entire equipment and the production and use of the equipment. Utility Model Content
[0005] To address the aforementioned issues, this utility model aims to provide a lamp string clamping mechanism for LED light string production, which optimizes the rollers and pressure rollers, utilizes height restrictions to achieve an opening at the clamping end, and improves the product's stability during use.
[0006] The technical problem solved by this utility model can be achieved by the following technical solution:
[0007] A lamp wire clamping mechanism for LED light string production includes a clamp, which includes a first clamping part and a second clamping part. The first clamping part and the second clamping part are hinged together, and a return spring is provided between the first clamping part and the second clamping part. A roller is provided on the first clamping part, and the roller is the highest part of the first clamping part. The upper part of the roller is used to abut against a pressure roller, and the clamping ends of the first clamping part and the second clamping part are in an open state through the pressure roller.
[0008] It also includes an opening retaining mechanism, which includes a first base, a first extension arm fixed on the first base, and a pressure roller portion located on the first extension arm. The bottom surface of the pressure roller portion is used to abut against the roller, and the height position of the roller is limited by limiting the height of the pressure roller portion. When the roller abuts against the pressure roller portion, the clamping ends of the first clamping portion and the second clamping portion are in an open state.
[0009] It also includes a pre-compression mechanism, which is located in front of the opening holding mechanism. The pre-compression mechanism includes a second base, a second extension arm fixed on the second base, and a pre-compression part located on the second extension arm. The bottom surface of the pre-compression part is used to abut against the roller.
[0010] The bottom surface of the pre-compression section is inclined, and the inclined surface continuously decreases in the direction of roller movement.
[0011] The pressure roller section is connected to the rear of the pre-compression section, and the bottom surface of the pressure roller section is at a height that is lower than or equal to the lowest height of the bottom surface of the pre-compression section.
[0012] The roller is a bearing, the outer ring of which is used to abut against the pressure roller, and the inner ring of which is used to fix the end of the first clamping part.
[0013] The first clamping part includes a first clamping body, a first clamping nozzle located at one end of the first clamping body, and an extension arm located at the other end of the first clamping body, with a roller mounted at the end of the extension arm; the second clamping part includes a second clamping part body, a second clamping nozzle located at one end of the second clamping part body, a hinge seat located in the middle of the second clamping part body, and a fixed base located at the other end of the second clamping part body, with the middle of the first clamping part body hinged to the hinge seat.

By utilizing the height limitation of the pressure roller, the clamping end can be in an open state after being subjected to force. Furthermore, the roller rolling structure makes the clamp movement smoother.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0026] Combination Figures 1 to 6 As shown, this utility model discloses a lamp wire clamping mechanism for LED light string production, including a clamp 100. The clamp 100 is used to clamp the lamp wire and can be arranged along the lamp wire routing direction according to the LED light string production equipment.
[0027] The clamp 100 includes a first clamping part 120 and a second clamping part 130, which are hinged together. A return spring 160 is provided between the first clamping part 120 and the second clamping part 130. The first clamping part 120 includes a first clamping body 122, a first clamping nozzle 121 located at one end of the first clamping body 122, and an extension arm 123 located at the other end of the first clamping body 122. A roller 110 is installed at the end of the extension arm 123, and the roller 110 is located at the highest position of the first clamping part 120. The second clamping part 130 includes a second clamping part body 135 and a return spring 160 located at the other end of the second clamping part body 135. The first clamping part 122 has a second clamping mouth 131 at one end, a hinge seat 132 located in the middle of the second clamping part body 135, and a fixed base 133 located at the other end of the second clamping part body 135. The middle part of the first clamping part body 122 is hinged to the hinge seat 132. The return spring 160 is located between the fixed base 133 and the extension arm 123 and is used to keep the first clamping mouth 121 and the second clamping mouth 131 in a clamping state. In the specific installation structure, the fixed base 133 is provided with a lower spring seat 134, and the lower surface of the extension arm 123 is provided with an upper spring seat 124. The two ends of the return spring 160 are respectively installed in cooperation with the upper spring seat 124 and the lower spring seat 134.
[0028] In combination with the above, the first clamping mouth 121 and the second clamping mouth 131 form the clamping end 150. The fixed base 133 is usually used to fix and install it with the machine body 500. The first clamping part 120 is a movable part. By pressing the extension arm 123, the first clamping mouth 121 can open relative to the second clamping mouth 131 to form an open structure. If there is no external force, since the return spring 160 is a compression spring, the tension of the return spring 160 is used to continuously provide an upward force to the extension arm 123, so that the first clamping mouth 121 and the second clamping mouth 131 are always in a closed state.
[0029] In conjunction with the above, a roller 110 is provided on the first clamping part 120. The roller 110 is the highest part of the first clamping part 120. The upper part of the roller 110 is used to abut against the pressure roller part 230. The pressure roller part 230 enables the clamping ends 150 of the first clamping part 120 and the second clamping part 130 to be in an open state. The structure of the pressure roller part 230 is optimized. The pressure roller part 230 is used to limit the height of the roller 110. After the roller 110 is restricted by the position of the pressure roller part 230, its downward pressure drives the extension arm 123 to press down. Because the position of the pressure roller part 230 is stable, the extension arm 123 presses down, causing the first clamping mouth 121 to rise relative to the second clamping mouth 131, forming an open state, which facilitates the introduction of the lamp wire. As the clamp 100 leaves the area where the pressure roller part 230 is located, the clamp returns to the clamping state due to the return spring 160, thus completing the clamping of the lamp wire.
[0030] The specific structure also includes an opening holding mechanism 200, which is installed in the LED string production equipment to match the wire mechanism 400, so that the lamp wire can be clamped by the clamp 100. The opening holding mechanism 200 includes a first base 210, a first extension arm 220 fixed on the first base 210, and a pressure roller 230 located on the first extension arm 220. The bottom surface of the pressure roller 230 is used to abut against the roller 110, and the height position of the roller 110 is limited by limiting the height of the pressure roller 230. When the roller 110 abuts against the pressure roller 230, the clamping ends 150 of the first clamping part 120 and the second clamping part 130 are in an open state, so that the wire can enter the opening of the clamping end 150. After the clamp 100 continues to move, it is disengaged from the area where the pressure roller 230 is located. The clamp returns to the clamping state due to the return spring 160, thus completing the clamping of the lamp wire.
[0031] Preferably, the device further includes a pre-compression mechanism 300, located at the front of the opening holding mechanism 200. The pre-compression mechanism 300 pre-compresses the included angle about to enter the opening holding mechanism 200. The pre-compression mechanism 300 includes a second base 310, a second extension arm 320 fixed to the second base 310, and a pre-compression part 330 located on the second extension arm 320. The bottom surface of the pre-compression part 330 abuts against the roller 110. The bottom surface of the pre-compression part 330 is inclined, and the inclined surface continuously decreases in the direction of travel of the roller 110. Several clamps 100 rotate with the device. As the roller 110 in the clamp 100 gradually enters the pre-compression mechanism 300 area, it gradually enters the bottom surface of the pre-compression part 330. The highest part of the pre-compression part 330 is preferably the same height as or slightly higher than the roller 110 in the clamping state, so as to facilitate the roller 110 in the clamp to enter the pre-compression part 330. As the clamp 100 continues to move forward, the roller 110 continues to descend, and the first clamping mouth 121 gradually opens. The pressure roller part 230 is connected to the rear of the pre-compression part 330. The height of the bottom surface of the pressure roller part 230 is lower than or equal to the lowest height of the bottom surface of the pre-compression part 330, so as to facilitate the roller 110 to enter the pressure roller part 230 through the connection.
[0032] Preferably, the roller 110 is a bearing, the outer ring 111 of the bearing is used to abut against the pressure roller 230, and the inner ring 112 of the bearing is used to fix the end of the first clamping part 120, which is convenient to combine with the clamp 100. It has the characteristics of simple structure and low manufacturing cost.
[0033] Preferably, the surface of the first clamping mouth 121 or / and the second clamping mouth 131 is provided with anti-slip texture 140 to improve the clamping stability of the lamp wire.
[0034] This invention optimizes the roller and pressure roller sections. By limiting the height of the pressure roller section, the clamping end can be in an open state after being subjected to force. The roller rolling structure makes the clamp movement smoother. Furthermore, the height limitation of the pressure section ensures that the clamp opening has a very stable opening size, which facilitates the insertion and clamping of wires and ensures the stability of the equipment operation.
[0035] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
